albin_huang — Wed, 20 Apr 2022 10:18:23 GMT

Hardware: I.MX8quadMax MEK

Software: imx-automotive-11.0.0_2.5.0

TFT-Panel: 12.3inch, 1920*720 2 channel lvds, Dual channel split mode (The panel needs two LVDS channels, CH0 for 1,3,5,7,... pixels and CH1 for 2,4,6,8,... pixels):

As I refer to 'https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/IMX8QM-LVDS-mirror-dual-mode-reference-patch/ta-p/1121478',

0001-iMX8QM-LVDS-add-mirror-dual-mode-support.patch.zip ,The patch not match with my downloaded code, especially in the 'drivers/gpu/drm/imx/imx-ldb.c',

below it my downloaded code,'nxp-opensource/kernel_imx/drivers/gpu/drm/imx'

How can I find the way to implement the theme?
